First of all, thank you! A lot of work went into this.
Here’s the link to the cards I created for the Exogorths:

Basically, they attack any ship within range 1. The larger (adolescent) Exogorth strikes with 2 attack dice and the smaller (juvenile) Exogorth strikes with 1 attack die. If a ship lands on an asteroid containing an Exogorth, that ship rolls for asteroid damage AND Exogorth damage.
The larger one was purchased from Mel Miniatures on Shapeways and the smaller one from Combatzone Scenery. They don’t come painted. I painted them myself.

It’s a long read but I hope some of you enjoy reading about it as much as I enjoyed designing it! Just about anything you could want to know about the scenario is in the article - inspirations, custom cards and dials, galleries galore, sources for materials used, etc.

Personally, I prefer the scale of X-wing Miniatures over Armada's and have absolutely zero interest in Legion.
Somebody did blend Armada with XWM in this awesome setup, though:

I've seen your Hammerhead Corvette and I'm jealous. Excellent work! I couldn't find a 3D print of the Rogue One Hammerhead when I designed this scenario, so I went with the CR12 and had it painted to look like the Lightmaker.
I'm still holding out hope for an official FFG Hammerhead. I now have a TIE Reaper to add to this scenario, if I ever run it again. I tend to design these things, play test them, and move on to my next project.

1900 points in all. The Rebels had 850 points. The Imperials had 1050 total points but the Lambda and 2 TIE Phantoms don’t spawn until the base is about to fall.

Here’s a picture log of how it went down. Look for the video of the exploded base where I display some masterful voice acting work. Lol.
In the coming days, I’ll do a full write-up for the Friday Night X-wing blog that will discuss my inspirations for the project and sources for the components used. The article will include a full components list, an outline of the mission objectives and special rules, high res images of all the custom cards, galleries explaining the custom mechanics of the custom Huge ships, a full written Batrep of every round, ship by ship, and the full picture log of this project. I took a whopping 82 pictures and one video.
This project has been around a year in the making and took a full five days to set up, play test and tear down. I’m pretty happy with how it all turned out. It’s basically just an excuse to throw all the cool things I’ve come across onto the mat and let the dice fly. After this, it’s on to my “Strike on Imperial Base Felucia” land/air scenario. The fun never ends!
